Cystopteris laurentiana, commonly called Laurentian bladderfern or St. Lawrence bladderfern, is a species of fern in the family Cystopteridaceae.[1] It is native to eastern North America, primarily in the Great Lakes-St. Lawrence lowlands, but there are also scattered occurrences in New England and Atlantic Canada.[2] It grows on cliffs composed of calcareous rocks, such as limestone, dolostone and diabase.[2][3][4]

Taxonomy

[edit]

Cystopteris laurentiana is a fertile allohexaploid hybrid between C. bulbifera (bulblet fern) and C. fragilis (fragile fern).[2] The scientific name is therefore sometimes written as C. × laurentiana, which denotes hybrid origin.
